Magneto-optical Drives

ALSO CALLED:
MO Drives,
DrivesDEFINITION: The magneto-optical (MO) drive is a popular way to back up files on a personal computer. As the term implies, an MO device employs both magnetic and optical technologies to obtain ultra-high data density. A typical MO cartridge is slightly larger than a conventional 3.5-inch magnetic diskette, and looks similar. But while the older type of magnetic diskette can store 1.44 megabytes (MB) of data, an

MAGNETO-OPTICAL DRIVES DEFINITION (continued): MO diskette can store many times that amount, ranging from 100 MB up to several gigabytes (GB).An MO system achieves its high data density by using a laser and a magnetic read/write head in combination. Both the laser and the magnet are used to write data onto the diskette. The laser heats up the diskette surface so it can be easily magnetized, and also to allow the region of magnetization to be precisely located and confined. A less intense laser is used to read data from the diskette. Data can be erased and/or overwritten an unlimited number of times, as with a conventional3.5-inch diskette.Examples Magneto-optical Drives definition sponsored by SearchStorage.com, powered by WhatIs.com an online computer dictionary
